Provedor de dados: 79
Autores: BARRAVIERA,B.; LOMONTE,B.; TARKOWSKI,A.; HANSON,L. Å.; MEIRA,D.A.
Thirty-one patients bitten by venomous snakes in Botucatu area (State of São Paulo - Brazil), sixteen by Bothrops spp. and fifteen by Crotalus durissus terrificus, were studied. The group comprised twenty-nine males and two females, ranging from fourteen to sixty-three years of age (mean 33 ± 15). Leukocytosis with neutrophilia and lymphopenia, increase of mucoproteins and C-reactive protein, decrease of total serum protein and albumin, were observed on the first day after the accident. In addition, increased serum levels of the cytokines IL-6 and IL-8, but not of IL-1&lt;FONT FACE="Symbol"&gt;b&lt;/FONT&gt; and TNF-&lt;FONT FACE="Symbol"&gt;a&lt;/FONT&gt;, were observed. The alterations were generally more intense in patients bitten by Crotalus durissus...

ABSTRACT The present study aimed to investigate the kinetics of acute phase proteins and cytokines in the serum of immunized or naive pigs following infection with a field isolate of foot-and-mouth disease (FMD) virus. Five-month-old SPF pigs were intramuscularly immunized with or without the 146S antigen (7.5 μg per head) purified from FMD virus (O/Andong/SKR/2010) and were subsequently challenged 30 days post-vaccination (dpv) with FMD virus on each footpad. Serum samples were obtained at 28 dpv and on days 1, 3, and 5 post-infection (dpi). At 28 dpv, the serum concentrations of C-reactive protein and tumor necrosis factor alpha (TNF-α) were higher in the immunized pigs compared with the non-immunized control pigs. Upon challenge, the levels of all...

Provedor de dados: 42
Autores: SANTOS,ANNA R.R. DOS; ALBUQUERQUE,RAFAELA R. DE; DORIQUI,MARIA J.R.; COSTA,GRACIOMAR C.; SANTOS,ANA PAULA S.A. DOS.
Acute intermittent porphyria is the most common acute porphyria caused by a decrease in hepatic porphobilinogen deaminase activity, resulting in an accumulation of delta-aminolevulinic acid and porphobilinogen. This disease shows nonspecific signs and symptoms that can be confused with other diseases, thereby making the diagnosis difficult. We report a case of acute intermittent porphyria, reviewing clinical and laboratory aspects, highlighting the hematological and biochemical parameters during and after the crisis. A female patient, aged 28 years, suffered two crises, both presenting gastrointestinal disorders. The second presented neuropsychiatric symptoms. The analysis of hematological and biochemical parameters during the second crisis showed anemia,...

Abstract: The systemic effect of chronic periodontitis (CP) has been suggested by several studies as an etiologic factor and modulator of diseases based on the changes in the inflammatory marker levels. This study aimed to investigate the relationship between the changes in clinical periodontal outcomes and serum biomarkers (CRP, IL-6, albumin and percentage of leukocytes) after non-surgical periodontal therapy in systemically healthy adults. An interventional study was conducted with a sample of 29 individuals without CP (control group) and 33 with CP (CP group). Periodontal clinical variables were recorded, and the serum levels of inflammatory markers were measured. Statistical analysis included the chi-square and Student’s t-tests and Pearson’s...

C-reactive protein-guided approach may shorten length of antimicrobial treatment of culture-proven late-onset sepsis: an intervention study
Provedor de dados: 55
Autores: Couto,Renato C.; Barbosa,José A. A.; Pedrosa,Tânia M.G.; Biscione,Fernando M.
Late-onset sepsis (LOS) (i.e., sepsis in a neonate after 72 hours of life) is associated with high mortality and significantly prolonged antibiotic exposure and hospital stay in neonates admitted to intensive care units (ICU). In this study, we assessed the reliability of serum C-reactive protein (CRP) as a determinant of antimicrobial treatment duration of LOS. From January 1996 to December 2002, all consecutive infants aged &lt;28 days admitted to a single medical-surgical ICU and diagnosed with primary LOS were enrolled in a prospective, intervention trial with historical controls. Only blood culture-positive LOSs were included. Exclusion criteria were: age &gt;28 days at diagnosis of LOS, development of site-specific infection, and central venous...

Provedor de dados: 55
Autores: Requejo,Henry I. Z.; Cocoza,Ana Maria.
Qualitative determination of C-reactive protein (CRP) was evaluated as a diagnostic method for community-acquired pneumonia. Paired serum and pleural fluid samples from child patients were examined with a CRP test, compared to bacterial cultures, counterimmunoelectrophoresis and immunoassay. The CRP test gave excellent parameters of sensitivity, specificity and predictive values for the diagnosis of bacterial pneumonia.

Dialysis water treated by reverse osmosis decreases the levels of C-reactive protein in uremic patients
Provedor de dados: 56
Autores: Thomé,F.S.; Senger,M.; Garcez,C.; Garcez,J.; Chemello,C.; Manfro,R.C.
Atherosclerosis is a major complication of chronic renal failure. Microinflammation is involved in atherogenesis and is associated with uremia and dialysis. The role of dialysate water contamination in inducing inflammation has been debated. Our aim was to study inflammatory markers in patients on chronic dialysis, before and 3 to 6 months after switching the water purification system from deionization to reverse osmosis. Patients had demographic, clinical and nutritional information collected and blood drawn for determination of albumin, ferritin, C-reactive protein (CRP), interleukin-6, and tumor necrosis factor-alpha in both situations. Acceptable levels of water purity were less than 200 colony-forming units of bacteria and less than 1 ng/ml of...

Provedor de dados: 56
Autores: Schaan,B.D.; Pellanda,L.C.; Maciel,P.T.; Duarte,E.R.; Portal,V.L.
Inflammatory markers have been associated with clinical outcome in patients with acute coronary syndrome (ACS). The present study evaluated the role of high-sensitivity C-reactive protein (CRP) measurements as a predictor of late cardiovascular outcomes after ACS. One hundred and ninety-nine ACS patients in a Coronary Care Unit from March to November 2002 were included and were reassessed clinically after ~3 years. Clinical variables and CRP levels were evaluated as predictors of major cardiovascular events (MACE, defined as the occurrence of cardiac death, ischemic stroke or myocardial infarction) and mortality. Statistical analyses included Cox multivariable analysis and survival curves (Kaplan-Meier). Of the 199 patients, 11 died within 1 month (5.5%)....

Correlates of C-reactive protein levels in young adults: a population-based cohort study of 3827 subjects in Brazil
Provedor de dados: 56
Autores: Nazmi,A.; Oliveira,I.O.; Victora,C.G.
The socio-demographic, behavioral and anthropometric correlates of C-reactive protein levels were examined in a representative young adult Brazilian population. The 1982 Pelotas Birth Cohort Study (Brazil) recruited over 99% of births in the city of Pelotas that year (N = 5914). Individuals belonging to the cohort have been prospectively followed up. In 2004-2005, 77.4% of the cohort was traced, members were interviewed and 3827 individuals donated blood. Analyses of the outcome were based on a conceptual model that differentiated confounders from potential mediators. The following independent variables were studied in relation to levels of C-reactive protein in sex-stratified analyses: skin color, age, family income, education, parity, body mass index,...

Effect of hepatitis C serology on C-reactive protein in a cohort of Brazilian hemodialysis patients
Provedor de dados: 56
Autores: Nascimento,M.M.; Bruchfeld,A.; Suliman,M.E.; Hayashi,S.Y.; Pecoits-Filho,R.; Manfro,R.C.; Pachaly,M.A.; Renner,L.; Stenvinkel,P.; Riella,M.C.; Lindholm,B.
Hepatitis C (HCV) is not an uncommon feature in hemodialysis (HD) patients and may be a cause of systemic inflammation. Plasma cytokine interleukin-6 (IL-6) is mainly produced by circulating and peripheral cells and induces the hepatic synthesis of C-reactive protein (CRP), which is the main acute phase reactant. The aim of this study was to investigate the influence of HCV on two markers of systemic inflammation, serum CRP and IL-6, in HD patients. The study included 118 HD patients (47% males, age 47 ± 13 years, 9% diabetics) who had been treated by standard HD for at least 6 months. The patients were divided into two groups depending on the presence (HCV+) or absence (HCV-) of serum antibodies against HCV. Serum albumin (S-Alb), plasma high sensitivity...

Depressive symptoms and C-reactive protein in a Brazilian urban community
Provedor de dados: 56
Autores: Dressler,W.W.; Balieiro,M.C.; Ribeiro,R.P.; Dos-Santos,J.E.
Psychological depression is an independent risk factor for coronary artery disease. C-reactive protein has been implicated as a mediator of the effect of psychological depression. Several studies have found that individuals, especially men, who report higher levels of psychological depression also have higher levels of C-reactive protein. The current study was undertaken to replicate these results in a Brazilian population, in which there is a much wider range of variation in both background characteristics (such as socioeconomic status) and coronary artery disease risk factors. A sample of 271 individuals was interviewed using the Center for Epidemiological Studies Depression Scale. Fasting blood samples were obtained and evaluated for C-reactive protein...

Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP), are related to coronary atherosclerosis, in addition to traditional coronary risk factors. Subjects of both genders aged 30 to 75 years (N = 116) were prospectively included if they had suffered a recent acute coronary syndrome (acute myocardial infarction or unstable angina pectoris requiring hospitalization) and if...

Autores: Oliveira,K.G.; von Zeidler,S.V.; Lamas,A.Z.; de Podestá,J.R.V.; Sena,A.; Souza,E.D.; Lenzi,J.; Lemos,E.M.; Gouvea,S.A.; Bissoli,N.S.
Pain is a common symptom in patients with cancer, including those with head and neck cancer (HNC). While studies suggest an association between chronic inflammation and pain, levels of inflammatory cytokines, such as C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-α), have not been correlated with pain in HNC patients who are not currently undergoing anticancer treatment. The purpose of this study was to examine the relationship between these inflammatory markers and perceived pain in HNC patients prior to anticancer therapy. The study group consisted of 127 HNC patients and 9 healthy controls. Pain was assessed using the Brief Pain Inventory (BPI), and serum levels of CRP and TNF-α were determined using the particle-enhanced turbidimetric...

Provedor de dados: 56
Autores: Assunção,L.G.S.; Eloi-Santos,S.M.; Peixoto,S.V.
The measurement of the serum concentration of the acute-phase reactant C-reactive protein (CRP) provides a useful marker in clinical practice. However, the distribution of CRP is not available for all age and population groups. This study assessed the distribution of high sensitivity-CRP (hs-CRP) by gender and age in 1470 elderly individuals from a Brazilian community that participates in the Bambuí Cohort Study. Blood samples were collected after 12 h of fasting and serum samples were stored at -70°C. Measurements were made with a commercial hs-CRP immunonephelometric instrument. More than 50% of the results were above 3.0 mg/L for both genders. Mean hs-CRP was higher in women (3.62 ± 2.58 mg/L) than in men (3.03 ± 2.50 mg/L). This difference was observed...
